Books have been stated on this matter, and the conflict and discussion about where the "hot" slot machines are installed in the casino are still bubbling – over sixty yrs after slot games were first placed in gambling houses.

The standard rule is that the more favourable slot machine games were placed just inside the main entrance of the casino; so that potential gamblers going by would see actual jackpot winners … be inspired to come unto the gaming floor … play. Our perspective is that this is definitely no longer the case.

The majority of the mega casinos presently are magnificent complexes … it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ one armed bandits close-by any entrances.

Another classic rule is that loose one armed bandits are put on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be encouraged to play. Importantly however, we find that this also is no longer a universal rule.

What casinos found over the years is that people walking down the busy aisles were frequently on the way to somewhere else. If they played slots at all, they would simply put in their loose change because they happened to be walking by. Win or lose, they would very often not stop to keep playing. And the very last thing a casino wants is for someone to win a jackpot by playing only a few coins and then not stay to put it all back in!

Today, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
